  1. 21. Towards stimuli-reformable paperboard and flipped classroom in chemistry education : A study of how to create a paper with controllable mechanical properties and a study in how the flipped classroom is used in chemistry education

    University essay from KTH/Skolan för teknikvetenskaplig kommunikation och lärande (ECE)

    Author : David Pettersson; [2017]
    Keywords : Alginate; Cationic cellulose nanofibrils; Cross-linking; Dialcohol cellulose;

    Abstract : Today, paper and paperboard is an important part of the packaging industry, as well as natural part of our daily lives. The alternatives to paper and paperboard is often produced from nonrenewable sources such as petroleum and as demands on sustainability increase in the packaging sector, it gives paper a desirable advantage over plastics.

  2. 22. Mechanical characterization of DuraPulp by means of micromechanical modelling

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY); Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Mustafa Al-Darwash; Emanuel Nuss; [2015]
    Keywords : Natural fiber composites NFC ; Polylactic acid PLA ; Micromechanical modeling; Modulus of Elasticity MOE ; Shear modulus; Poisson’s ratio;

    Abstract : Södra DuraPulp is a relatively new eco-composite, made from natural wood fibers and polylactic acid (PLA), which comes from corn starch. Until now, there are only few applications for DuraPulp, mainly in the area of design. To find new fields of application, more knowledge about its mechanical material properties are of great interest. READ MORE

  3. 23. The role of ICT in optimizing reverse textile supply chains

    University essay from Akademin för textil, teknik och ekonomi

    Author : Iuliia Tsiupka; Alicia Mason; [2015]
    Keywords : reverse textile supply chain; reverse textile logistics; Information Communications Technology; sustainability; last mile problem; first mile problem; textile recycling; textile recollection;

    Abstract : Fast fashion and over consumption within the textile industry has led to a serious depletion of natural resources. The current rate of population growth and consumption is unsustainable. In result, there is a growing interested in sustainable solutions, one of which is reverse supply chains. READ MORE

  4. 24. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Nima Esmaeili; Shahrzad Javanshir; [2014]
    Keywords : Biobased thermoset; thermoset poly lactic acid; biobased composite; natural fiber; viscose;

    Abstract : Lactic acid based thermoset were synthesised by reacting lactic acid with glycerol andfunctionalizing lactic acid branches by methacrylic anhydride. Resins with different chainlength were prepared and their thermo mechanical properties were examined through DMAanalysis and their molecular structures were analyzed by NMR method and their viscositywere investigated through rheometry analysis and three monomers were selected as the bestchain length.

  5. 25. Ultrasound induced cavitation and resonance amplification using adaptive feedback Control System

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vipul. vijigiri; Taraka Rama Krishna Pamidi; [2014]
    Keywords : Acoustic cavitation; optimization; FFT analysis; pure sine excitation; Sonotrode or ultrasonic horn; High intensity ultrasound; Sound pressure level SPL Acoustic pressure field; Feedback control; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Acoustic cavitation in fluids using high powered ultrasound has been of great interest in industries and biomedical engineering. The need for high-intensity focused ultrasound (sound with frequencies between 20 kHz to 10 MHz) and modeling of such systems has drawn great attention in engineering. READ MORE
